SECTION 1 INTRODUCTION

1.1 Description

The OMEGALUXTMCRFC, CRWS, CRRS, and CRFP Series of vacuum
formed ceramic heaters are produced using high quality, high purity,
vacuum formed ceramic with a low sodium inorganic bond. In the
CRRS and CRFP Series, helically wound quality iron-chrome-aluminum
ribbon elements are mounted in ridges which permit heat dissipation in
three directions, thereby, transferring more radiant heat energy to the
work chamber and load. By using this grooved surface, these
OMEGALUX products can more than triple the effective radiant surface.
Sections 4.3 through 4.6 show the different types of heaters that are
available from OMEGALUX as well as their specifications.

1.2 Recommended Maximum Operating Temperature

Maximum operating temperature is limited to 1800 degrees F degrees
C. For more information refer to the material safety data sheet
(MSDS-0135).

1.3 Tolerance

Because of the nature of ceramic fiber, there will be a potential variance
of ±1/4" in the size of the heaters. These products initially may shrink at
higher temperatures. This shrinkage could be up to 4% for temperatures
up to 980˚ C, resistance tolerance is ±5%.

SECTION 2 UNPACKING

Remove the Packing list and verify that all equipment has been
received. If there are any questions about the shipment, please call the
OMEGALUX Customer Service Department at 1-800-622-2378.

Upon receipt of shipment, inspect the container and equipment for any
signs of damage. Take particular note of any evidence of rough handling
in transit. Immediately report any damage to the shipping agent.

FOR YOUR INFORMATION

Care must be taken in handling the vacuum formed
ceramic heaters due to the materials used in
manufacturing them.

SECTION 3 WIRING PROCEDURES

3.1 General

1. Be sure that the line voltage matches the heater’s rated voltage.

2. Electric wiring to heater must be installed in accordance with Local
and National Electric Code.

3.2 Heating Element Power Connection

1. Figures 3-1, 3-2, 3-3, and 3-4 should be closely adhered to, to insure
maximum element life. L1 and L2 indicate the two power input
wires from the user’s power source. Polarity MUST always be
observed. L1 and L2 should never be connected adjacent to each
other. Failure to observe polarity may cause premature heater
failure.

2.

Recommended are mechancial terminations such as SPLIT BOLT
connections or TERMINAL STRIPS. For the all heating element
listed in this manual, the wire leads become brittle after being
brought up to maximum operating temperature (980˚ C). Caution
should be taken in handling heaters after initial operation.

3. Lead wire extending from the heater elements may be bent to
form to your specific needs. Caution must be taken so that the
integrity of the internal connection is maintained to prolong the
life of the heating element. To avoid placing excessive stress on
this junction, use soft nose pliers to hold the lead wire secure
where the wire exits from the heating element and then bend.

112

CAUTION AND WARNING!!

Fire and electrical shock may result if products are used
improperly or installed or used by non-qualified persons.
Refer to the inside front cover for additional warranty
information. The CR Series heaters are intended for
RADIANT heat only.

NEVER LET MATERIAL COME INTO

DIRECT CONTACT WITH THE FACE OF THE HEATER.

NOTE: The carrier will not honor any claims unless all shipping material is saved for

their examination. After examining and removing contents, save packing material and
carton in the event reshipment is necessary.
